2 MAIN WORKING AREAS
Energy Renewable Innovative Efficiency Energy Sources Energy technologies
Innovative Security of Mobility energy supply
3 Initial situation in companies & for building owners
The existing energy efficiency potentials are existing, but: • No financial resources for high investments • Lack of personal resources and know-how • Uncertainty about the real energy saving
Energy Service Provider can support!
4 Definition of ESCOs
Energy Service Provider means a natural or legal person who delivers energy services or other energy efficiency improvement measures in a final customer’s facility or premises Energy Efficiency Directive EED 2012/27/EU, Article 2 (24)
e.g. contracting, energy consultancy, energy audits
5 Best Practise in AT: Awareness Raising
A list of providers has been published: http://www.contracting-portal.at/show.php?nid=0&mid=21&srchCont=srch • Energy supply companies • Component manufacturers • Plumbers – and/or cooperation of SMEs! • Operating companies • Control technology companies • Building service providers • etc.
6 Contracting – legal basis
= signing a contract between an ESCO (Energy Service Company) and a client • Energy Supply Contracting • Investments to provide energy (e.g. new biomass boiler for room heating) • Refinancing by billing for the consumed energy • Energy Performance Contracting (EPC) • Measures to save energy • Refinancing by saved energy costs • transfer of technical risks from client to ESCO
7 Energy Supply Contracting
Building owner‘s annual costs Total costs contracting Baseline – actual costs Total costs (old): Energy rate (acc. to consumption): Fuel Consumption bound costs Electricity price adjustment Maintenance Fixed rate: Reinvestment Investment and funding Personell costs Price adjustment (salary, maintenance) Miscellaneous Risks, Operation-bound costs Time Actual state Investment End of contract Energy supply contract
8 Advantages of contracting for the client
• Professional planning, maintenance, energy saving measures • Savings and quality guarantee • Outsourcing of operational risks • „No“ capital investment • Wide range of building services • Focusing on core competencies • Efficient communication • Energy efficiency, eco-friendliness, sustainability, role model function
9 Barriers
• Lack of motivation – Lack of interest for energy savings – Investor-user problem (owner has not to pay for energy supply costs) – Staff cuts (e.g. facility management, outsourcing) • Lack of information – Technical, economic know-how – Effects on operation procedures – Know-how of grants and consultancy possibilities
10 Barriers
• Financial barriers • Limited financial means • In many cases: long payback times • Trend of energy prices (forecast, consideration in the contract) • Lack of commitment • Commitment of the building-user is essential for the success of the project!
11 Best practise in Austria: Large contracting initiative of the federal government (1/2)
• provided by a co-operation group consisting of Federal Ministry for Science, Research and Business (BMWFW) and the Federal Real Estate Agency (BIG- Bundesimmobiliengesellschaft) • BIG is responsible for the management of Federal Buildings: federal schools and government buildings (ministries) as well as office areas (public buildings and court buildings) to optimize public utility properties using energy-saving contracting to enable energy-saving measures • In so-called „tendering pools“, several buildings are combined into one contracting project
12 Best practise in Austria: Large contracting initiative of the federal government (2/2)
• ALREADY: Contracting for appr. 320 federal buildings • Thermal refurbishment financed and performed by the Federal Buildings Association, other energy savings measures via contracting (since 2001) • Performance and plant contracting, contract duration 7 – 15 years • http://www.big.at/projekte/projektdatenbank/ • Effects: – ¼ of all refurbishment investments for energy related refurbishment measures – Reduction of energy costs 35 Mio. €
– Reduction of CO2-emissions by 130,000 tons per year
13 Best practise: „Transparense project“ - to increase transparency of EPC (1/2)
http://transparense.eu/eu/home/welcome-to- transparense-project
14 Best practise: „Transparense project“ - to increase transparency of EPC (2/2)
• to increase the transparency and trustworthiness of Energy Performance Contracting (EPC) markets throughout Europe • Established a Code of Conduct for the implementation of EPC projects and its 20 national modifications in the participating countries • defines the fundamental principles for EPC projects preparation and implementation - as a guarantee of the quality of EPC projects • In Austria: a new label is under preparation! • To ensure the quality of the process and the documents! And to help getting high quality loans from the bank

Best practise: GREEN INFRASTRUCTURE at MA 48 - PUBLIC BUILDING | Einsiedlergasse 2, 1050 Vienna
• Contracting together with IÖB – use new technologies! BIG Building! (Vienna has a UHI Strategy!) • Building is equipped with a green façade on the street side. • 2,850 meters of aluminium trays were installed on 850 m2 façade – with 17,000 plants • great potential for dust filtration and air improvement, rain and wind protection as well as a positive influence on the sound and heat
insulation. www.green4cities.com 17 •
Microclimate - GREEN INFRASTRUCTURE at MA 48 - PUBLIC BUILDING | Einsiedlergasse 2, 1050 Vienna
• It was completed in 2009, and since then, a monitoring program on the vertical wall has been running. • This research provides information about impacts on building physics and microclimatic performance of the façade, water consumption, transpiration and the overall development of the vegetation layers over time.
